GRACE ICE & WATER SHIELD Self-adhered roofing underlayment Product Description

Grace Ice & Water Shield® self-adhered roofing underlayment is a premier membrane composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of high density cross laminated polyethylene. The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. In addition, embedded in the membrane is a Ripcord® split release on demand feature. The full width membrane is supplied in three full-width roll sizes. See the Product Data chart for product information. Membrane strips are also available in 75 ft (22.9 m) long rolls at widths of 6 in. (150 mm), 9 in. (225 mm), 12 in. (300 mm) and 18 in. (450 mm).

Features & Benefits

Easy to handle and apply—The self-adhesive membrane bonds firmly to the roof deck without heat or special adhesives. Ripcord® split release on demand is a unique and patented feature that makes Grace Ice & Water Shield® roofing underlayment is easier to apply by giving the applicator the option to split the release liner in half. Faster application of the membrane in the straight-aways, as well as ease of membrane positioning in detailed areas (valleys, around dormers, etc.), are just some of the benefits. Foldless release paper—The foldless release paper provides multiple performance enhancements: fewer edge catches, 180° pull-back, ease of membrane cutting (single cuts) and membrane positioning, quicker “one-man installs” resulting in an easier, more productive release. Seals around nails—The rubberized asphalt layer in Grace Ice & Water Shield® membrane seals around roofing nails, resisting leakage caused by water back-up behind ice dams, or from winddriven rain. Dual barrier protection—Rubberized asphalt and polyethylene are combined to form two waterproofing barriers providing maximum protection. Membrane will not crack, dry out or rot—Grace Ice & Water Shield® roofing underlayment resists attacks from fungus and bacteria; maintains its integrity for long lasting protection. Protects under all standard sloped roof coverings—Grace Ice & Water Shield® roofing underlayment protects under slate, tile, cedar shakes or metal, as well as under conventional asphalt shingles. Slip resistant surface—Grace Ice & Water Shield® self-adhered membrane has a slip resistant embossed surface to maximize traction and safety for applicators.

®

Proven track record—Grace Ice & Water Shield® roofing underlayment is the name brand in roofing underlayments with a 35-year track record of protecting roofs from ice dams and winddriven rain. Reroofable—Unlike granular surfaced membranes, Grace Ice & Water Shield® smooth surface underlayment will not adhere to the underside of the exposed roof covering. Grace Ice & Water Shield® membrane can be applied over the old Grace underlayment (except over Grace Basik®, Grace Tri-Flex® and Grace SYN 15™) In retrofit applications, making re-roofing easier, less costly (since there is no need for removing the existing underlayment), more durable and environmentally friendly (as the structural deck remains intact avoiding the need to purchase additional wood decking). Grace technical support—Grace Ice & Water Shield® roofing underlayment is backed by a team of local technical support personnel that help ensure every application goes smoothly.

Guidelines for Use

Grace Ice & Water Shield® roofing membrane is used as an underlayment for sloped roofs to resist water penetration due to water back-up behind ice dams or wind-driven rain. Grace Ice & Water Shield® underlayment also offers leak protection in trouble prone spots like valleys, skylights, protrusions and other flashing areas.

35

Ice Dams Grace Ice & Water Shield® roofing underlayment should be used in conjunction with roof designs that minimize ice dam formation. In cold climates, it is particularly important to provide proper insulation and ventilation to reduce the size of ice dams and to avoid interior condensation. Cathedral ceilings must include ventilation between rafters to allow for air flow to a ridge vent. Well ventilated cold roof designs are particularly important in alpine regions to reduce the size of ice dams which could contribute to structural damage. Several variables will influence the height of ice dams and the membrane coverage required. 1. Climate—The annual snow fall will affect the amount of membrane needed. 2. Slope—On a low slope, ice dams will extend farther inward from the roof edge. 3. Overhang—A wide overhang will require more membrane to reach the appropriate point on the roof. 4. Insulation and ventilation—A very well insulated building with a cold, well ventilated attic will have smaller ice dams. 5. Valleys—Any valleys formed by projections such as dormers or roof direction changes are likely to trap more snow and cause larger ice dams. 6. Exposure—A northern exposure or shaded areas will generally contribute to larger ice dams. While gutters may make it easier for an ice dam to start, large dams can occur on roofs with no gutters. Removing snow from a roof edge or installing heat cables may not prevent ice dam formation, but may shift the location of the ice dam. Under certain conditions, a dam can form at the edge of the remaining snow. Local building codes should be consulted for specific requirements.

metal, concrete, or gypsum sheathing. Remove dust, dirt, loose nails, and old roofing materials. Protrusions from the deck area must be removed. Decks shall have no voids, damaged, or unsupported areas. Wood planks should be closely butted together. Repair deck areas before installing the membrane. Prime concrete, masonry surfaces and DensGlass Gold® with Perm-A-Barrier® WB Primer. Prime wood composition and gypsum sheathing with Perm-A-Barrier® WB Primer if adhesion is found to be marginal (refer to Technical Letter 12, Use on Oriented Strand Board (OSB) Roof Sheathing). Apply PermA-Barrier® WB Primer at a rate of 250–350 ft2/gal (6–8 m2/L). Priming is not required for other suitable surfaces provided that they are clean and dry. Membrane Installation Apply Grace Ice & Water Shield® underlaymentin fair weather when the air, roof deck, and membrane are at temperatures of 40°F (5°C) or higher. Apply roof covering material at temperatures of 40°F (5°C) or higher. Cut the membrane into 10–15 ft (3–5 m) lengths and reroll loosely. Peel back 1–2 ft (300–600 mm) of release liner, align the membrane, and continue to peel the release liner from the membrane. Press the membrane in place with heavy hand pressure. Side laps must be a minimum of 3.5 in. (90 mm) and end laps a minimum of 6 in. (150 mm). For valley and ridge application, peel the release liner, center the sheet over the valley or ridge, drape, and press it in place. Work from the center of the valley or ridge outward in each direction and start at the low point and work up the roof. Alternatively, starting with a full roll of membrane, unroll a 3–6 ft (1–2 m) piece of membrane leaving the release liner in place. Align the membrane and roll in the intended direction of membrane application. Carefully cut the release liner on top of the roll in the cross direction being careful not to cut the membrane. Peel back about 6 in. (150 mm) of the release liner in the opposite direction of the intended membrane application exposing the black adhesive. Hold the release liner with one hand and pull the roll along the deck with the release liner, leaving the applied membrane behind. Use the other hand to apply pressure on the top of the roll. Stop frequently to press the membrane in place with heavy hand pressure. When finished with the roll go back to the beginning, reroll and pull the remaining release paper from the material, finishing the installation. For successive membrane courses, align the edge of the release liner with the dashed line provided on the surface of the membrane to achieve the 3.5 in. (90 mm) side lap. Consistent with good roofing practice, install the membrane such that all laps shed water. Always work from the low point to the high point of the roof. Apply the membrane in valleys before the membrane is applied to the eaves. Following placement along the eaves, continue application of the membrane up the roof. The membrane may be installed either vertically or horizontally. Use smooth shank, electro-plated galvanized nails for fastening shingles to get the best seal. Hand nailing generally provides a better seal than power-activated nailing. If nailing of the membrane is necessary on steep slopes during hot or extreme cold weather, backnail and cover the nails by overlapping with the next sheet. Extend the membrane on the roof deck above the highest expected level of water back-up from ice dams and above the highest expected level of snow and ice on the wall sheathing on vertical side walls (dormers) and vertical front walls for ice dam protection. Consider a double layer of membrane

in critical areas, such as along the eaves or in valleys and in climates where severe ice dams are anticipated. Apply the membrane to the entire roof deck for wind-driven rain protection. Apply a new layer of Grace Ice & Water Shield® underlayment directly over the old Grace underlayment in retrofit applications following the standard membrane application procedure. Precautions & Limitations • Slippery when wet or covered by frost. • Consistent with good roofing practice, always wear fall protection when working on a roof deck. • Release liners are slippery. Remove from work area immediately after membrane application. • Do not leave permanently exposed to sunlight. Cover within 30 days. • Place metal drip edges or wood starter shingles over the membrane. • Do not fold over the roof edge unless the edge is protected by a drip edge, gutter or other flashing material. • Do not install on the chamfered edges of wood plank. • Do not install directly on old roof coverings. • Certain product applications are prohibited in hot desert areas in the southwestern United States. Check with your Grace Construction Products representative. • Check with the manufacturer of the metal roofing system for any special requirements when used under metal roofing. Do not install directly under roof coverings especially sensitive to corrosion, such as zinc, without providing proper ventilation. • Do not install under copper, Cor-Ten®, or zinc metal roofing in high altitudes. These roofs can reach extremely high temperatures due to the low reflectivity, high absorption, and high conductivity of the metals. Use Grace Ultra™ underlayment for these roof types. Check with your Grace Construction Products representative. • Provide proper roof insulation and ventilation to help reduce ice dams and to minimize condensation. Grace Ice & Water Shield® membrane is an air and vapor barrier. • Repair holes, fishmouths, tears, and damage to membrane with a round patch of membrane extending past the damaged area 6 in. (150 mm) in all directions. If fasteners are removed leaving

holes in the membrane, they must be patched. The membrane may not self-seal open fastener penetrations. • Do not install fasteners through the membrane over unsupported areas of the structural deck, such as over the joints between adjacent structural panels. • Due to its slight asphaltic odor, do not apply where the membrane is exposed to interior living space. Refer to product literature for more complete information. • Not compatible with EPDM or TPO; use Grace Ultra™ underlayment for tie-ins (refer to Technical Letter 5, Chemical Compatibility). • Not compatible with polysulfides, flexible PVC, or high concentrations of resin (pitch). For more information, refer to Technical Letter 5. Code Compliance Grace Ice & Water Shield® roofing underlayment meets the following standards: • Underwriters Laboratories Inc.

Report NOA 12-1115.02 • Florida State Approval Report No. FL289-R3

Ice Dams Water from melting snow over the heated portion of the house runs down the roof. It freezes at the cold eave and an ice dam begins to form preventing drainage.

As the ice dam grows, water is trapped behind it and backs up under the shingles. Eventually it reaches the roof deck and leaks through, damaging the interior of the structure.

Grace Ice & Water Shield® underlayment resists this leakage because of the seal around the fasteners, ability to make watertight laps, and the membrane’s bond to the deck.

Sloped roofs are not waterproof. They protect structures by shedding rain water.

Storm-driven winds can cause sloped roof coverings to lift. Rain can then be easily driven under the roof covering directly to the unprotected roof deck where it causes leaks and damage to the interior of the structure.

Grace Ice & Water Shield® roofing underlayment applied beneath the sloped roof covering helps prevent winddriven rain from entering the structure.

GRACE ICE & WATER SHIELD HT Self-adhered roofing underlayment for high temperature applications ®

Product Description

Grace Ice & Water Shield® HT high temperature self-adhered roofing underlayment is a premier membrane designed to deliver premium in-place performance for high temperature applications. It is composed of two waterproofing materials—an innovative and proprietary rubberized asphalt adhesive combined with a high performance polymeric film with UV barrier properties. The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. In addition, embedded in the membrane is a split release on demand feature called Ripcord®.

Features & Benefits

Today’s sloped roof designs utilize more insulation, incorporate long-lasting roof coverings and tend to have lengthy construction cycles. The many variables that contribute to roof top temperatures; insulation, facing, pitch, color, etc., make it difficult to predict what kind of heat profile the roof top will experience. Choosing an underlayment that will perform under all of these demanding conditions is essential to a successful roof design. Grace Ice & Water Shield® HT underlayment was specifically designed to meet the challenge of these high-temperature applications. It is an environmentally conscious solution that provides both confidence and design flexibility. High temperature resistance—Rubberized asphalt will not flow, even at temperatures as high as 260°F (127°C). Extended exposure—Can be left exposed for up to 120 days. Superior adhesion—The self-adhered membrane bonds firmly to the roof deck without heat or special adhesives. Ripcord is a unique, patented feature that makes Grace Ice & Water Shield® HT underlayment easier to apply by giving the applicator a split release on demand. Faster application of the membrane in the straight-aways, as well as ease of membrane positioning in detailed areas (valleys, around dormers, etc.), are just some of the benefits. Foldless release paper—The foldless release paper provides multiple performance enhancements: fewer edge catches, 180° pull-back, ease of membrane cutting (single cuts) and membrane positioning, quicker “one-man installs” resulting in an easier, more productive release. Seals around fasteners—The rubberized asphalt layer in Grace Ice & Water Shield® HT membrane seals around roofing nails and other fasteners, resisting leakage caused by water back-up behind ice dams or wind-driven rain. Dual barrier protection—Rubberized asphalt is combined with

polymeric film to form two waterproofing barriers providing maximum protection. Membrane will not crack, dry out or rot—Grace Ice & Water Shield® HT membrane resists attacks from fungus and bacteria; maintains its integrity for long lasting protection. Protects under all standard sloped roof coverings—Grace Ice & Water Shield® HT underlayment protects under slate, tile, cedar shakes, metal and conventional asphalt shingles. Slip resistant surface—Grace Ice & Water Shield® HT underlayment has a slip resistant embossed surface to maximize traction and improve safety. Reroofable—Unlike some granular surfaced membranes, Grace Ice & Water Shield® HT roofing underlayment will not adhere to the underside of the exposed roof covering. It can be applied over the old Grace underlayment (except over Grace Basik®, Grace Tri-Flex® and Grace SYN 15™) in retrofit applications, making reroofing easier, less costly, more durable and environmentally friendly (as the structural deck remains intact avoiding the need to purchase additional wood decking).

Hold the release liner with one hand and pull the roll along the deck with the release liner, leaving the applied membrane behind. Use the other hand to apply pressure on the top of the roll. Stop frequently to press the membrane in place with heavy hand pressure. When finished with the roll go back to the beginning, reroll and pull the remaining release paper from the material, finishing the installation. For successive membrane courses, align the edge of the release liner with the dashed line provided on the surface of the membrane to achieve the 3.5 in. (90 mm) side lap. Consistent with good roofing practice, install the membrane such that all laps shed water. Always work from the low point to the high point of the roof. Apply the membrane in valleys before the membrane is applied to the eaves. Following placement along the eaves, continue application of the membrane up the roof. The membrane may be installed either vertically or horizontally. Use smooth shank, electro-plated galvanized nails for fastening shingles to get the best seal. Hand nailing generally provides a better seal than power-activated nailing. If nailing of the membrane is necessary on steep slopes during hot or extreme cold weather, backnail and cover the nails by overlapping with the next sheet. Extend the membrane on the roof deck above the highest expected level of water back-up from ice dams and above the highest expected level of snow and ice on the wall sheathing on vertical side walls (dormers) and vertical front walls for ice dam protection. Consider a double layer of membrane

in critical areas, such as along the eaves or in valleys and in climates where severe ice dams are anticipated. Apply the membrane to the entire roof deck for wind-driven rain protection. Apply a new layer of Grace Ice & Water Shield® HT membrane directly over the old Grace underlayment in retrofit applications following the standard membrane application procedure. Precautions & Limitations • Slippery when wet or covered by frost. • Consistent with good roofing practice, always wear fall protection when working on a roof deck. • Release liners are slippery. Remove from work area immediately after membrane application. • Do not leave permanently exposed to sunlight. Cover within 120 days. • Place metal drip edges or wood starter shingles over the membrane. • Do not fold over the roof edge unless the edge is protected by a drip edge, gutter or other flashing material. • Do not install on the chamfered edges of wood plank. • Do not install directly on old roof coverings. • Certain product applications are prohibited in hot desert areas in the southwestern United States. Check with your Grace Construction Products representative. • Check with the manufacturer of the metal roofing system for any special requirements when used under metal roofing. Do not install directly under roof coverings especially sensitive to corrosion, such as zinc, without providing proper ventilation. • Do not install under copper, Cor-Ten®, or zinc metal roofing in high altitudes. These roofs can reach extremely high temperatures due to the low reflectivity, high absorption, and high conductivity of the metals. Use Grace Ultra™ butyl-based underlayment for these roof types. Check with your Grace Construction Products representative. • Provide proper roof insulation and ventilation to help reduce ice dams and to minimize condensation. Grace Ice & Water Shield® HT underlayment is an air and vapor barrier. • Repair holes, fishmouths, tears, and damage to membrane with a round patch of membrane extending past the damaged area 6 in. (150 mm) in all directions. If fasteners are removed leaving holes in the membrane, they must be patched. The membrane may not self-seal open fastener penetrations. • Do not install fasteners through the membrane over unsupported areas of the structural deck, such as over the joints between adjacent structural panels. • Due to its slight asphaltic odor, do not apply where the membrane is exposed to interior living space. Refer to product literature for more complete information. • Not compatible with EPDM or TPO; use Grace Ultra® for tie-ins (refer to Technical Letter 5, Chemical Compatibility). • Not compatible with polysulfides, flexible PVC, or high concentrations of resin (pitch).

Ice Dams Water from melting snow over the heated portion of the house runs down the roof. It freezes at the cold eave and an ice dam begins to form preventing drainage.

As the ice dam grows, water is trapped behind it and backs up under the shingles. Eventually it reaches the roof deck and leaks through, damaging the interior of the structure.

Grace Ice & Water Shield® HT membrane resists this leakage because of the seal around the fasteners, ability to make watertight laps, and the membrane’s bond to the deck.

Sloped roofs are not waterproof. They protect structures by shedding rain water.

Storm-driven winds can cause sloped roof coverings to lift. Rain can then be easily driven under the roof covering directly to the unprotected roof deck where it causes leaks and damage to the interior of the structure.

Grace Ice & Water Shield® HT membrane applied beneath the sloped roof covering helps prevent wind-driven rain from entering the structure.

GRACE ULTRA™ Self-adhered roofing underlayment for the highest temperature applications

Product Description

Guidelines for Use

Grace Ultra™ roofing underlayment is composed of two waterproofing materials—an aggressive butyl rubber based adhesive backed by a layer of high density cross laminated polyethylene. The product is 30 mils (0.76 mm) thick making it easy to handle and apply. The unique, advanced adhesive formulation offers premium adhesion to the roof deck, high quality laps, superior seal around roofing fasteners, and outstanding high temperature stability. The adhesive is backed by a protective plastic release liner that protects its adhesive quality. The release liner is easily removed allowing the adhesive to be bonded tightly to the roof deck. The membrane comes in a 198 ft2 (18.4 m2) roll, and measures 34 in. (864 mm) wide.

Grace Ultra™ membrane can be used as a sloped roof underlayment to help protect against leakage from water that builds up behind ice dams, or from wind-driven rain in applications where the membrane must withstand the highest in-service temperatures for extended periods of time. High Temperature Applications Grace Ultra™ membrane is the appropriate product for all applications where superior heat resistance is

Features & Benefits Easy to handle and apply—The membrane bonds firmly to the roof deck and forms high quality laps. Self sealing—The membrane meets key building code standards for nail sealability of self-adhered roofing underlayments. Heat resistance—The membrane is specially formulated to resist temperatures up to 300°F without degradation of the butyl adhesive. Better Chemical Resistance— Compatible with low slope roofing materials such as EPDM and TPO Slip resistant surface—The slip resistant surface maximizes traction for safety without compromising the water integrity of the laps. Plastic release—Plastic is easy to remove and easy to dispose of. Reroofable—Unlike some granular surfaced membranes, Grace Ultra™ underlayment will not adhere to the underside of the exposed roof covering making reroofing easier and less costly. Grace expertise—Grace is the recognized leader in self-adhered roofing underlayments and is the manufacturer of Grace Ice & Water Shield® roofing underlayment.

needed. In addition, Grace Ultra™ underlayment is the appropriate product for use under certain types of metal roofs (those employing copper, zinc, or Cor-Ten® panels). These metal roofs tend to readily conduct heat to the underlayment making them more likely to expose the membrane to high temperatures. It is up to the contractor and specifier to decide what level of performance is required based on the guidelines provided. Wind-Driven Rain Sloped roofs are not waterproof. They protect structures by shedding rain water. Storm-driven winds can cause sloped roof coverings to lift. Rain can be easily driven under the roof covering directly to the unprotected deck where it causes leaks and damage to the interior of the structure. Grace Ultra™ membrane applied beneath the sloped roof covering helps prevent winddriven rain from entering the structure. For wind-driven rain protection, full coverage with Grace Ultra™ underlayment is recommended. Since Grace Ultra™ underlayment is a vapor barrier, the roof construction must allow for proper ventilation in full roof coverage applications. Ice Dams For ice dam protection, Grace Ultra™ membrane should be adhered at the edge of the roof deck by the eaves. The membrane should be applied to a point on the roof deck above the highest expected ice dam. Several variables influence the height of ice dams and the membrane coverage required. Local building codes should be consulted for specific requirements. Variables influencing the height of ice dams include climate (particularly the annual snowfall), slope, overhang, valleys, how well the structure is insulated and ventilated, and exposure (sun vs. shade). In addition to placement along the eaves, Grace Ultra™ membrane can be used to help prevent roof leaks in a handful of danger zones like in valleys, at the rake edges, and around chimneys and skylights.

Installation Procedure Surface Preparation Install Grace Ultra™ membrane directly on a clean, dry, continuous structural deck. Some suitable deck materials include plywood, wood composition, wood plank, metal, concrete, or gypsum sheathing. For all other substrates, contact your local Grace representative. Remove dust, dirt, loose nails, and old roofing materials. Protrusions from the deck area must be removed. Decks shall have no voids, damaged, or unsupported areas. Repair deck areas before installing the membrane. Prime concrete, masonry surfaces and DensGlass Gold® with Perm-A-Barrier® WB Primer. Prime wood composition and gypsum sheathing with Perm-A-Barrier® WB Primer if adhesion is found to be marginal (refer to Technical Letter 12, Use on Oriented Strand Board (OSB) Roof Sheathing). Apply PermA-Barrier® WB Primer at a rate of 250–350 ft2/gal (6–8 m2/L). Priming is not required for other suitable surfaces provided that they are clean and dry. Membrane Installation Apply Grace Ultra™ membrane in fair weather when the air, roof deck, and membrane are at temperatures of 40°F (5°C) or higher. Apply roof covering material at temperatures of 40°F (5°C) or higher. Cut the membrane into 10–15 ft (3–5 m) lengths and reroll loosely. Tack/secure the end of the roll with a nail. Peel back 1–2 ft (300–600 mm) of release liner, align the membrane, and continue to peel the release liner from the membrane. Press the membrane in place with heavy hand pressure. Side laps must be a minimum of 3.5 in. (90 mm) and end laps a minimum of 6 in. (150 mm). For valley and ridge application, peel the release liner, center the sheet over the valley or ridge, drape, and press it in

GRACE TRI-FLEX High performance roofing underlayment ®

Grace Tri-Flex® mechanically-attached roofing underlayment is a high performance water-shedding underlayment, designed to overcome the shortcomings of traditional roofing felt. It is stronger than #30 felt and withstands high wind conditions; it is lighter than #30 felt and covers more area. The product is mechanically attached to the roof and can be used alone or in conjunction with Grace self-adhered underlayments. Grace roofing underlayment provides a stable base for the application of mechanically-attached roof coverings and serves as a secondary water shed to help prevent leaks if water penetrates the primary roof covering. The product may also be used to temporarily “dry in” the structure for a period of 6 months before the roof construction is finished or if the primary roof coverings become damaged. Grace underlayment is suitable for application as part of all major roof systems.

Features & Benefits Below are some of the major benefits of Grace roofing underlayment compared to conventional #30 roofing felt: It’s lighter and covers more area—A roll of underlayment is around half the weight of #30 felt, and has nearly 5 times the coverage. It’s stronger—Grace Tri-Flex® roofing underlayment is 20 times stronger than felt and won’t tear away from nails even in high winds. It’s more durable—Grace underlayment can be left

Product Description Grace underlayment is a high strength woven synthetic roofing underlayment coated with a layer of UV stabilized polyolefin. This composition creates a tough, weather-resistant membrane that has been proven under some of the harshest conditions in North America. Grace Tri-Flex® roofing underlayment is available in 10 sq rolls (48 in. wide x 250 ft long).

Product Advantages • Lighter and covers more area • Stronger • More durable • Slip resistant under wet conditions • Suitable for use under all major roof coverings • Facilitates faster and easier installation • 25 Year Warranty 51

exposed for up to 6 months. It doesn’t dry out or rot at high temperatures. It doesn’t crack or become brittle at low temperatures. It’s slip resistant—Grace roofing underlayment is formulated for excellent skid-resistance even in wet conditions. Suitable for use under all major roof coverings—Grace Tri-Flex® mechanically-attached underlayment can be used under shingles, tiles, slate, metal and cedar shakes. Refer to subsequent sections for more details. Facilitates faster and easier installation—The lighter rolls make the one-person application fast and easy. It also means fewer trips up the ladder and lower labor costs. Grace technical support—Grace Tri-Flex® underlayment is backed by a team of local technical support personnel that help ensure every application goes smoothly.

Installation Guidelines

4. Grace Tri-Flex® underlayment is attached to the roof with roofing nails or staples both having 1-inch diameter plastic/ metal caps or other fasteners approved by Grace, spaced at 8 inches on center (oc) on both side and end laps in normal wind zones. In high wind zones or coastal applications, double the fastening to 4 inches oc. In all cases fasten at 24 inches oc down the middle of the roll in the field of the roof. Capped nails and staples may be hand or machine applied. Nails or staples without caps cannot be used. 5. Where seams or joints require sealant or adhesive, use a high quality, low solvent, asbestos free plastic roofing cement meeting ASTM D4586 Type 1, Federal Spec SS-153 Type 1 (Asbestos Free). Consult your local Grace representative for more details. 6. Install drip edge at eaves under underlayment and at rake over underlayment. 7. Installation of the roof covering can proceed imme

1. The roof deck must be swept clean and be smooth and dry before installation begins. 2. Grace membrane is laid horizontally (parallel to eave), starting at the bottom of the roof, with printed side up and with 4-inch side laps and 6-inch end laps. Side laps run with the flow of water in a shingling manner. 3. Grace underlayment should not be used at slopes less than 2:12, provided the slope is also acceptable to the primary roof covering. On slopes of less than 3:12, Grace membrane should be half-lapped a full 24 inches over the underlying course, shingle style.

Used only capped nails or capped staples. Lay with a minimum 6 inches end lap. Use a 4 inch side lap. Follow printed guidelines for easy installation. Fasten at 24 inches oc in the middle of the roll.

GRACE ROOF DETAIL MEMBRANE Self-adhered flexible flashing Premium Protection at Roof Detail Areas Roof details, such as valleys, rake edges, chimneys, ridges, skylights and dormer walls, can greatly enhance the beauty of any home. Unfortunately, they are also some of the most leak-prone areas on a roof. The results can range from stained walls and ceilings to severe water damage, costing thousands of dollars to repair. Unless the leakage problem is corrected, damage will continue to result. Granular underlayments may lack the ability to conform to many common roof details, creating the potential for leaks. Grace Roof Detail Membrane is a flexible product that conforms tightly to these transition areas, reducing the risk of water infiltration. Grace Roof Detail Membrane is the only product available today designed specifically for waterproofing critical roof detail areas.

future tie-ins. The membrane also features square edge cuts and measure markings on the face to further simplify layout and installation. The membrane is composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of high-density, cross-laminated polyethylene. The rubberized asphalt surface is backed with a release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck and walls. The membrane is available in 9 in. and 18 in. widths. See the Product Data chart for more information.

Product Description Grace Roof Detail Membrane is a premier membrane based on the Grace Ice & Water Shield® roofing underlayment technology. The new membrane has the Ripcord® split-release on demand feature placed in the center and near the edge (18 in. width) for easy installation at the transition areas as well as allowing for

Product Advantages • Easy to handle and apply • Seals around nails • Membrane will not crack, dry out or rot • Protects under all standard sloped roof coverings • Slip resistant surface • Proven track record • Reroofable • Inhibits corrosion • Grace technical support 59

Features & Benefits

Installation Procedure

Easy to handle and apply—The self-adhesive membrane bonds firmly to the substrate without heat or special adhesives. Water cannot seep under the membrane. Watertight seams are easily formed.

Surface Preparation Install Grace Roof Detail Membrane directly on a clean, dry, continuous structural substrate. Some suitable substrates are plywood, wood composition, metal, concrete or gypsum sheathing. For all other substrates, contact your Grace representative. Remove dust, dirt, loose nails and old roofing materials. Protrusions from the substrate area must be removed. Substrates shall have no damaged or unsupported areas, or voids. Repair substrate before installing the membrane.

Ripcord® split-release on demand is a unique, patented feature that makes Grace Roof Detail Membrane easy to apply by giving the applicator a split release on demand. The split release makes positioning in detail areas easy by minimizing the amount of adhesive exposed during installation. Both the 9 in. and 18 in. rolls contain Ripcord® split-release on demand placed at the center and near the edges to simplify application of the membrane at angled transitions, allowing the applicator to select the amount of adhesive to be exposed during installation. Seals around nails—The rubberized asphalt layer in Grace Roof Detail Membrane seals around roofing nails, resisting leakage caused by water back-up behind ice dams, or from wind-driven rain.

Use Grace Roof Detail Membrane on all critical areas

Membrane will not crack, dry out or rot—Grace Roof Detail Membrane resists attacks from fungus and bacteria; maintains its integrity for long lasting protection. Protects under all standard sloped roof coverings—Grace Roof Detail Membrane protects under slate, tile, cedar shakes or metal, as well as under conventional asphalt shingles. Slip resistant surface—Grace Roof Detail Membrane has a slip resistant embossed surface to maximize traction and safety for applicators. Proven track record—Grace Roof Detail Membrane is based on Grace Ice & Water Shield® underlayment, the name brand in roofing underlayments with over 30 years of protecting roofs from ice dams and wind-driven rain. Reroofable—Unlike some granular-surfaced membranes, Grace Roof Detail Membrane will not adhere to the underside of the exposed roof covering. Grace Roof Detail Membrane can be applied over the old Grace underlayment (except over Grace Basik® underlayment) in retrofit applications, making reroofing easier, less costly—since there is no need for removing the existing underlayment—more durable and environmentally friendly—as the substrate remains intact, avoiding the need to purchase additional wood substrate. Inhibits corrosion—Grace Roof Detail Membrane isolates metal roof components from new corrosive wood preservatives.

Vycor enV-S ®

™

Fully-adhered weather resistive barrier sheet

Description

Vycor enV-S sheet applied, vapor permeable weather resistive barrier consists of a unique breathable carrier film coated with an adhesive that is specially designed to maintain vapor permeability. Keeping walls dry is the key to preventing rot of structural elements and mold growth. Vycor® enV-S™ fullyadhered barrier protects against wind driven rain. Vycor® enV-S™ vapor permeable membrane allows the wall system to “breathe”, and water vapor to escape. Unlike conventional building wraps, installation of Vycor® enV-S™ weather resistive barrier requires no mechanical fastening, and it seals around nails used to install siding and other wall elements. This results in exceptionally low levels of air leakage, and improved energy efficiency of the building. ®

Safety Refer to product label and Material Safety Data Sheet before use. All users should acquaint themselves with this information prior to working with the material. Carefully read detailed precaution statements on the product labels and MSDS before use. MSDSs can be obtained from our web site at graceconstruction.com, graceresidential.com or by contacting Grace toll free at 866-3333SBM (3726).

contact with the substrate to prevent water from migrating under the membrane. Continue the membrane into all openings in the wall area, such as windows, doors, etc., and terminate at points that will prevent interior visibility. The installation must be made continuous at all framed openings, such as windows, doors, etc. Flash framed openings with Vycor® Plus Flashing and overlap onto Vycor® enV-S™ membrane in a shingled manner. Coordinate installation of the Vycor® enV-S™ membrane with the roofing trade to ensure continuity with the roofing system at this critical transition area. In certain applications such as on soffits or ceilings, back nail the membrane along the side lap prior to installing the next sheet of membrane to ensure positive contact to the substrate. At the end of each working day, if the wall has been only partially covered, apply a bead of compatible sealant along the top edge of the membrane at its termination to prevent vertical drainage of precipitation from penetrating the end and undermining the membrane adhesion. Tool the compatible sealant to ensure it is worked into the surface. Inspect the membrane before covering and repair any punctures, damaged areas or inadequately lapped seams.

Temperature Vycor® enV-S™ weather resistive barrier may be applied only in dry weather when air and surface temperatures are above 40°F (5°C). Surface Preparation Vycor® enV-S™ weather resistive barrier can typically be installed over clean and dry wood sheathing (plywood or OSB) without the aid of an adhesive primer. In those cases when adhesion appears to be marginal, or when installing over cementitious or glass-mat faced substrates, use Grace Perm-A-Barrier® Primer Plus to aid in creation of a tenacious bond to the substrate. Apply Perm-A-Barrier® Primer Plus by brush or roller application. Allow Perm-A-Barrier® Primer Plus to dry until surface becomes tacky. Drying times may vary depending on temperature and humidity conditions. Refer to Perm-A-Barrier® Primer Plus product data sheet for installation recommendations. Surface must be smooth, clean, dry and free of voids, loose nails, sharp protrusions or other matter that will hinder the adhesion or regularity of the wall membrane installation. Clean loose dust or dirt from the surface to which the wall membrane is to be applied by wiping with a clean, dry cloth or brush. OSB and plywood must have moisture content below 12%. Membrane Application Cut membrane into easily handled lengths. Apply membrane horizontally or vertically to plywood or OSB substrates. All side and end laps must be overlapped a minimum of 2 in. (51 mm) and all laps must be water-shedding The membrane must be pressed firmly into place with a hand roller as soon as possible, ensuring continuous and intimate

Membrane Repairs

Limitations

Repairs must be made using Vycor® enV-S™ barrier sized to extend 6 in. (150 mm) in all directions from the perimeter of the affected area. If repairs are required, carefully cut out affected areas and replace in similar procedure as outlined in the text above. The repair piece must be pressed into place with a hand roller as soon as possible to ensure continuous and intimate contact with the substrate. Apply a bead of compatible sealant along the top edge of the repair piece.

Vycor® enV-S™ weather resistive barrier must not be applied in areas where it will be permanently exposed to UV light and must be covered within a reasonable amount of time, not to exceed 90 days.

FLORPRUFE 120 Integrally bonded vapor protection for slabs on grade ®

Description

Florprufe® 120 is a high perfor-mance vapor barrier with Grace’s Advanced Bond TechnologyTM that forms a unique seal to the underside of concrete floor slabs. Comprising a highly durable polyolefin sheet and a specially developed, non-tacky adhesive coating, Florprufe 120 seals to liquid concrete to provide integrally bonded vapor protection. Florprufe exceeds ASTM E1745 Class A rating.

Advantages

• Forms a powerful integral seal to the underside of concrete slabs • Protects valuable floor finishes such as wood, tiles, carpet and resilient flooring from damage by vapor transmission • Direct contact with the slab complies with the latest industry recommendations • Remains sealed to the slab even in cases of ground settlement • Ultra low vapor permeability • Durable, chemical resistant polyolefin sheet • Lightweight, easy to apply, kick out rolls • Simple lap forming with mechanical fixings or tape

Use

Florprufe 120 is engineered for use below slabs on grade with moisture-impermeable or moisture-sensitive floor finishes that require the highest level of vapor protection. Florprufe complies with the latest recommendations of ACI Committees 302 and 360, i.e. for slabs with vapor sensitive coverings, the location of the vapor barrier should always be in direct contact with the slab1. 1

ACI 302.1R-96

The membrane is loose laid onto the prepared sub-base, forming overlaps that can be either mechanically secured or taped. The unique bond of Florprufe to concrete provides continuity of vapor protection at laps. Alternatively, if a taped system is preferred, self-adhered Preprufe® Tape can be used to overband the laps. Slab reinforcement and concrete can be placed immediately. Once the concrete is poured, an integral bond develops between the concrete and membrane.

Installation

Health & Safety Refer to relevant Material Safety Data Sheet. Complete rolls should be handled by 2 persons. Florprufe 120 can be applied at temperatures of 25ºF (-4ºC) or above. Membrane installation is unaffected by wet weather. Installation and detailing of Florprufe 120 are generally in accordance with ASTM E1643-98.

Prepare substrate in accordance with ACI 302.1R Section 4.1. Install Florprufe 120 over the leveled and compacted base. Place the membrane with the smooth side down and the plastic release liner side up facing towards the concrete slab. Remove and discard plastic release liner. End laps should be staggered to avoid a build up of layers. Succeeding sheets should be accurately positioned to overlap the previous sheet 2 in. (50 mm) along the marked lap line. Laps 1. Mechanical fastening method— To prevent the membrane from moving and gaps opening, the laps should be fastened together at 39 in. (1.0 m) maximum centers. Fix through the center of the lap area using 0.5 in. (12 mm) long washer-head, self-tapping, galvanized screws (or similar) and allowing the head of the screw to bed into the adhesive compound to self-seal. It is not necessary to fix the membrane to the substrate, only to itself. Ensure the membrane lays flat and no openings occur. (See Figure 1.) Additional fastening may be required at corners, details, etc. Continuity is achieved once the slab is poured and the bond to concrete develops. OR 2. Taped lap method— For additional security use Grace Preprufe Tape to secure and seal the overlaps. Overband the lap with the 4 in. (100 mm) wide Preprufe Tape, using the lap line for alignment. Remove plastic release liner to ensure bond to concrete.
